1/2 In Bronze Dual Check Valve, Intermediate Atmospheric Vent, Female Union Inlet/Outlet Connection, Viega Propress (R) Adaptors

This 1/2 inch dual check valve with atmospheric vent prevents the reverse flow of hot or cold polluted water from entering into the potable water supply. This valve is designed for continuous pressure non-health hazard applications in smaller supply lines, such as laboratory equipment, processing tanks, sterilizers, dairy equipment, and specifically for boiler feed lines. It consists of a bronze body with stainless steel internal parts, integral strainer, two durable tight seating rubber check valves, and NPT female inlet and outlet connections with Viega ProPress (R) connection adapters.
